Thank you guys, "set_field" works now, the input command line is: """ ovs-ofctl add-flow -O OpenFlow13 br-int "hard_timeout=0,idle_timeout=0,priority=65535,cookie=17142212024999476593,in_port=2,table=0,ip,reg2=0,actions=set_field:16->ip_dscp,load:55->NXM_NX_REG2[0..5],resubmit(,0)" """
The command "ovs-ofctl dump-flows br-int -O OPENFLOW10" results: """ cookie=0xede55f036e85fd71, duration=1.537s, table=0, n_packets=0, n_bytes=0, priority=65535,ip,reg2=0,in_port="patch-tun" actions=mod_nw_tos:64,load:0x37->NXM_NX_REG2[0..5],resubmit(,0) """ "ovs-ofctl dump-flows br-int -O OPENFLOW13" results: """ cookie=0xede55f036e85fd71, duration=115.497s, table=0, n_packets=0, n_bytes=0, priority=65535,ip,reg2=0,in_port="patch-tun" actions=set_field:16->ip_dscp,load:0x37->NXM_NX_REG2[0..5],resubmit(,0) """ On Tue, Jul 13, 2021 at 12:14 AM Ben Pfaff <b...@ovn.org> wrote: > > On Mon, Jul 12, 2021 at 03:13:13PM +0800, LIU Yulong wrote: > > Recently, I tested OpenStack Neutron with DSCP marking functions.
